Suitable for unattended draining of compressed air dryers, aftercoolers, receivers and other pressure vessels.

NO AIR LOSS DRAIN
A stainless steel float assembly equipped with a magnetic reed switch rises with the fluid level until its upper limit is reached. At this level, the reed switch signals a solid state relay which in turn signals a solenoid valve to be energized. As the valve opens, the line pressure forces the fluid in the reservoir to exit. As the float lowers with the reservoir fluid level, a lower limit is reached causing the reed switch to signal the closing of the solenoid valve allowing NO AIR to escape
